Thanks! I made the “frame” myself. The sides are just black painters tape and the top and bottom are pieces I cut from a corrugated plastic board (this one). I super glued the pieces on and stuck the painting on the wall with upholstery tacks (this one). I used upholstery tacks because they’re way longer and sturdier. It’s super affordable! Hope that all made sense.

I cut the center out from a corrugated plastic board (I misremembered it as being cardboard) (this one). I super glued the plastic board on the excess canvas and stuck the painting on the wall with upholstery tacks (this one). I used upholstery tacks because they’re way longer and sturdier. I also used them because my walls are textured and double stick tape doesn't stick. It’s super easy and affordable! Hope that all made sense.
